if you want to have a complete redundancy even from an electrical point of view, Cisco offers the StackPower solution (XPS).

StackPower share the power supplies to all slots of a Cisco StackWise.

In this example we create two PowerStack in a StackWise of 5. Below the configuration:

!         
stack-power stack S-POWER-A
stack-power stack S-POWER-B
!         
stack-power switch 1
 stack S-POWER-A
stack-power switch 2
 stack S-POWER-A
stack-power switch 3
 stack S-POWER-A
stack-power switch 4
 stack S-POWER-B
stack-power switch 5
 stack S-POWER-B
!
